“… many conservatives don't necessarily doubt that we'll eventually see thousands of new border agents, and 700 miles of fencing somewhere along the southern border, and new technology deployed to monitor illegal entry points, and some form of E-Verify, and a revamped entry-exit visa system.”
What? Who are the "many" fools who "don't necessarily doubt"? They must live inside the beltway. Rational people KNOW they will never do this stuff in a way to clamp down on the illegals.
